Learning outcomes
|
Optical properties of important rock-forming of minerals microscopy.
The students will: - apply methods of specimen preparation (thin sections) - learn physical background to optical microscopy (refractive index, the travel of light through optically isotropic and anisotropic media, colour and pleochroism) - understand interaction of polarized light with minerals (light interference, extinction of polarized light) - be able to describe optical properties of optically uniaxial and biaxial minerals - be able to determine the main rock-forming minerals on the base of optical properties - be able to describe in detail the mineral composition and microstructure of common magmatic, metamorphic and sedimentary rock types - understand the basics of reflected light microscopy
